Engineering Selection Recommendations

Primary Equivalent: TE Connectivity 5-146274-4 is the direct equivalent to the obsolete 5-146286-4. Both parts share identical electrical and mechanical specifications, including contact length, insulation height, and operating temperature range. The 5-146274-4 maintains active product status and RoHS compliance, making it the preferred replacement for direct substitution in existing designs.

Secondary Substitutes - Sullins Connector Solutions: The Sullins PBC04 and PEC04 series connectors provide functional alternatives with the following considerations:

PBC04 Series (Gold-Plated Mating Contacts):

PBC04SFAN: Shortest post length (0.120"), suitable for compact PCB applications
PBC04SFBN: Medium post length (0.220"), standard through-hole depth
PBC04SFCN: Extended post length (0.320"), for thicker PCB assemblies
PBC04SFDN: Long post length (0.420"), for multi-layer board stacks
PBC04SFEN: Extended post length (0.520"), for maximum board separation

PEC04 Series (Tin-Plated Mating Contacts):

PEC04SFAN: Shortest post length (0.120"), matches original contact finish specification
PEC04SFBN: Medium post length (0.220")
PEC04SFCN: Extended post length (0.320")
PEC04SFDN: Long post length (0.420")

All Sullins alternatives feature:

Enhanced operating temperature range (-65°C ~ 125°C)
Phosphor Bronze contact material for improved durability
Polybutylene Terephthalate insulation material
Active product status with ROHS3 compliance
Increased insulation height (0.100" vs. 0.090")

Selection between PBC04 and PEC04 series depends on mating contact finish requirements. PEC04 series maintains tin plating consistent with the original 5-146286-4 specification. PBC04 series offers gold plating for enhanced corrosion resistance in demanding environments.

Frequently Asked Questions (FAQ)

Q: Can I directly replace TE Connectivity 5-146286-4 with 5-146274-4? A: Yes. The 5-146274-4 is the direct equivalent with identical specifications. The primary difference is product status: 5-146274-4 is active while 5-146286-4 is obsolete. Both share the same connector type, pitch, contact configuration, and operating parameters.

Q: What is the difference between PBC04 and PEC04 series connectors? A: The primary difference is the mating contact finish. PBC04 series features gold-plated mating contacts (10.0µin thickness), while PEC04 series features tin-plated mating contacts (100.0µin thickness). Both series use phosphor bronze contact material and polybutylene terephthalate insulation. The PEC04 series maintains closer alignment with the original tin-plated specification of the 5-146286-4.

Q: How do I select the correct post length variant? A: Post length selection depends on PCB thickness and stacking requirements. PBC04SFAN and PEC04SFAN (0.120" post) are suitable for standard single-layer or thin PCB applications. Longer variants (SFBN, SFCN, SFDN) accommodate thicker PCBs or multi-layer board stacks. Measure your PCB thickness and select the post length that provides adequate penetration for solder joint formation without excessive protrusion.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts are ROHS3 compliant. The original 5-146286-4 is ROHS3 compliant, and the equivalent 5-146274-4 is RoHS compliant. All Sullins alternatives (PBC04 and PEC04 series) are ROHS3 compliant.

Q: What is the operating temperature difference between the original part and substitutes? A: The original 5-146286-4 operates from -65°C to 105°C. The equivalent 5-146274-4 maintains this range. All Sullins substitute parts (PBC04 and PEC04 series) extend the upper limit to 125°C, providing enhanced thermal performance for high-temperature applications.

Q: Can I use PBC04 series (gold-plated) in place of the original tin-plated connector? A: Yes, with consideration for contact finish requirements. Gold plating provides superior corrosion resistance and is generally compatible with tin-plated mating surfaces. However, if your design specifically requires tin-plated contacts, the PEC04 series maintains this specification.

Q: What is the insulation material difference? A: The original 5-146286-4 uses Liquid Crystal Polymer (LCP) insulation. The equivalent 5-146274-4 also uses LCP. All Sullins alternatives use Polybutylene Terephthalate (PBT) insulation. Both materials meet UL94 V-0 flammability requirements and are suitable for standard through-hole applications.

Q: Are there any mechanical compatibility issues when substituting? A: All listed parts maintain identical pitch (0.100"), contact shape (square), and mounting type (through-hole). The primary mechanical variation is post length and overall contact length. Verify that your PCB hole pattern and mating connector accommodate the selected post length variant. Insulation height increases from 0.090" to 0.100" in Sullins alternatives, which may affect board-level clearances in compact designs.

Q: What is the current rating for all these connectors? A: All listed parts maintain a 3A current rating per contact, consistent with the original 5-146286-4 specification.
