Engineering Selection Recommendations
Primary Recommendation: TE Connectivity 6-146274-6
The 6-146274-6 is the manufacturer-recommended substitute from TE Connectivity. This part maintains identical pitch, position count, and row configuration while offering active product status. The transition from kinked pin to straight solder termination is functionally equivalent for through-hole PCB assembly. Operating temperature range (-65°C to 105°C) matches the original specification. Contact finish transitions from Tin-Lead to Tin, which maintains electrical performance. RoHS3 compliance status is not specified for this part but should be verified during procurement. This option provides the most direct replacement path with minimal design impact.
Secondary Recommendation: Amphenol ICC 54101-T3016LF
The 54101-T3016LF from the BERGSTIK® series offers active product status with RoHS compliance and extended operating temperature range (-65°C to 125°C). This part maintains all critical mechanical and electrical parameters. Contact material transitions from Copper Alloy to Phosphor Bronze, which provides equivalent electrical conductivity. Tin contact finish on both mating and post surfaces ensures compatibility. Current rating of 3A per contact matches the original specification. This option provides enhanced temperature performance and regulatory compliance.
Tertiary Recommendation: Amphenol ICC 68024-116HLF
The 68024-116HLF from the BERGSTIK® II series provides active product status with RoHS compliance and REACH compliance documentation. This part features enhanced current rating (5A) and voltage rating (110V), providing margin above the original 3A specification. Contact length post dimension (0.150") differs from the original (0.125"), which may require PCB layout verification. Gold contact finish (30.0µin) provides superior corrosion resistance compared to the original Tin-Lead finish. This option is suitable for applications requiring enhanced electrical performance and regulatory documentation.
Compliance Considerations:
- The original 1-104428-4 is ROHS3 compliant; verify RoHS status of selected substitute during procurement
- 3M 2316 series parts are RoHS non-compliant; use only if legacy system requirements mandate non-compliant components
- Amphenol ICC parts (54101 and 68024 series) are RoHS compliant and REACH affected; suitable for new designs and regulated applications
- All recommended substitutes maintain UL94 V-0 flammability rating
Frequently Asked Questions (FAQ)
Q: Can the 1-104428-4 be directly replaced with the 6-146274-6?
A: Yes. Both parts share identical pitch (2.54mm), position count (16), row configuration (1), contact type (male pin), and mounting method (through hole). The termination method transitions from kinked pin to straight solder pin, which is functionally equivalent for PCB assembly. Operating temperature ranges are identical. No design modifications are required.
Q: What is the difference between kinked pin and straight solder termination?
A: Kinked pin termination features a bent lead that provides mechanical retention during PCB insertion. Straight solder termination uses a linear lead for insertion into plated through holes. Both methods achieve equivalent electrical connection and mechanical stability after solder reflow. Straight termination is more common in modern manufacturing and offers improved automated assembly compatibility.
Q: Are the 3M 2316 series parts suitable replacements?
A: The 3M 2316-6211-TB, 2316-6211-TG, and 2316-6211-TP parts meet all critical mechanical and electrical parameters. However, these parts are RoHS non-compliant. Use these parts only in applications where legacy component specifications are required or RoHS compliance is not mandated. For new designs, select RoHS-compliant alternatives from TE Connectivity or Amphenol ICC.
Q: What is the significance of contact finish differences (Tin vs. Tin-Lead vs. Gold)?
A: Contact finish affects corrosion resistance and long-term reliability in specific environments. Tin-Lead provides baseline performance and is the original specification. Tin offers equivalent performance with lead-free compliance. Gold provides superior corrosion resistance in high-humidity or corrosive environments but increases cost. All three finishes are electrically equivalent for standard applications. Select based on environmental requirements and regulatory compliance needs.
Q: Can parts with different insulation heights be substituted?
A: The original 1-104428-4 has insulation height of 0.090" (2.29mm). Most substitutes feature 0.100" (2.54mm) insulation height. This 0.010" difference may affect mating connector alignment or stacking height in multi-connector assemblies. Verify mating connector specifications and PCB layout clearances before substitution. Contact TE Connectivity or Amphenol ICC technical support if stacking height is critical to your application.
Q: What is the difference between BERGSTIK® and BERGSTIK® II series?
A: BERGSTIK® series (54101 parts) represents the standard product line with 3A current rating and -65°C to 125°C operating temperature. BERGSTIK® II series (68004 and 68024 parts) offers enhanced specifications including 5A current rating and 110V voltage rating. BERGSTIK® II parts feature different contact post lengths (0.107" to 0.150" vs. 0.120" in BERGSTIK®). Select BERGSTIK® II for applications requiring higher current capacity or voltage rating.
Q: Are all substitute parts available in the same packaging options?
A: Packaging varies across substitutes. The original 1-104428-4 packaging is not specified. Substitutes are available in Bulk, Bag, and Tape & Reel (TR) packaging. Verify packaging requirements for your procurement and assembly process. Tape & Reel packaging (54101-S3016A01LF) is suitable for automated assembly. Bulk or Bag packaging (68024-116HLF, 77311-122-16LF) is suitable for manual assembly or lower-volume applications.
Q: What is the impact of Phosphor Bronze vs. Copper Alloy contact material?
A: The original 1-104428-4 uses Copper Alloy contacts. Amphenol ICC BERGSTIK® series parts use Phosphor Bronze contacts. Phosphor Bronze provides superior spring characteristics and wear resistance compared to Copper Alloy, resulting in longer contact life and improved mating cycle durability. Electrical conductivity is equivalent. Phosphor Bronze is preferred for high-cycle mating applications.
Q: Can the 1-104428-4 be used interchangeably with parts having different voltage ratings?
A: The original 1-104428-4 has 30VAC voltage rating. Substitutes with higher voltage ratings (68024-116HLF at 110V) are backward compatible and can be used in applications rated for 30VAC or lower. Substitutes without specified voltage ratings should be assumed to meet or exceed the original 30VAC specification. Verify voltage rating specifications during procurement if your application requires specific voltage compliance documentation.
