Substitute Part Grouping Explanation

Substitute parts for the 68683-225LF are qualified based on the following core parameters that determine functional equivalence:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 50 positions at 0.100" (2.54mm) mating pitch
Row Configuration: 2 rows with 0.100" (2.54mm) row spacing
Mounting & Termination: Through-hole solder termination with push-pull fastening
Contact Finish: Gold-plated mating surface
Electrical Performance: Voltage rating and contact material (phosphor bronze)
Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance

The identified substitutes (2-215307-5 and BCS-125-L-D-TE) meet these core criteria, though variations exist in insulation material, contact finish thickness, and packaging format. These differences do not affect functional interchangeability in standard board-to-board applications.

Engineering Selection Recommendations

All three parts maintain active product status and comply with UL94 V-0 flammability requirements and RoHS standards. Selection between the 68683-225LF and its substitutes should be based on the following factors:

68683-225LF (Amphenol ICC Dubox™): Specified for -65°C to 125°C operating range with 1000V voltage rating. Suitable for applications requiring extended low-temperature performance and higher voltage tolerance. PPS insulation material provides chemical resistance.

2-215307-5 (TE Connectivity AMPMODU HV-100): Offers higher gold plating thickness (31.5µin) on mating contacts, providing enhanced contact durability. Kinked pin termination option available. ROHS3 compliant. Tray packaging format. Higher inventory availability (1361 units).

BCS-125-L-D-TE (Samtec Tiger Claw™ BCS): Specifies 4.6A per contact current rating and 475VAC voltage rating. LCP insulation material offers superior dimensional stability. Slightly taller insulation height (0.290"). ROHS3 compliant. Tube packaging.

All three parts are electrically and mechanically compatible for standard board-to-board interconnect applications where the core 50-position, 0.100" pitch configuration is required.

Frequently Asked Questions (FAQ)

Q: Can the 2-215307-5 directly replace the 68683-225LF?

A: Yes. Both connectors share identical position count (50), mating pitch (0.100"), row configuration (2 rows at 0.100" spacing), mounting type (through-hole), termination method (solder), and fastening type (push-pull). The primary differences are insulation material (Polyester vs. PPS), contact finish thickness, and packaging format (Tray vs. Tube). These differences do not affect functional interchangeability in standard applications.

Q: Can the BCS-125-L-D-TE directly replace the 68683-225LF?

A: Yes. The BCS-125-L-D-TE meets all core electrical and mechanical requirements: 50 positions, 0.100" pitch, 2-row configuration, through-hole solder termination, and push-pull fastening. Differences include insulation material (LCP vs. PPS), slightly taller insulation height (0.290" vs. 0.276"), and specified current/voltage ratings. These variations do not prevent functional replacement in standard board-to-board applications.

Q: What is the significance of contact finish thickness differences?

A: Contact finish thickness affects contact durability and mating cycle life. The 68683-225LF specifies 15.0µin (0.38µm) gold plating, while the 2-215307-5 provides 31.5µin (0.80µm). Thicker plating generally extends contact life in high-cycle mating environments. The BCS-125-L-D-TE specifies 10.0µin (0.25µm). Selection depends on application mating cycle requirements.

Q: How do insulation material differences affect substitution?

A: The 68683-225LF uses PPS (Polyphenylene Sulfide), the 2-215307-5 uses Polyester, and the BCS-125-L-D-TE uses LCP (Liquid Crystal Polymer). All are glass-filled and UL94 V-0 rated. Material selection affects chemical resistance, dimensional stability, and temperature performance. PPS and LCP offer superior performance in demanding environments. Polyester is suitable for general-purpose applications. Substitution is valid when application environment requirements are met by the alternative material.

Q: What packaging format differences exist?

A: The 68683-225LF and BCS-125-L-D-TE are supplied in Tube packaging, while the 2-215307-5 is supplied in Tray packaging. Packaging format affects handling, storage, and automated assembly compatibility. Tube packaging is suitable for manual assembly and lower-volume applications. Tray packaging is optimized for high-speed automated pick-and-place assembly. Functional performance is identical regardless of packaging format.

Q: Are all three parts RoHS compliant?

A: Yes. The 68683-225LF is RoHS Compliant. The 2-215307-5 and BCS-125-L-D-TE are both ROHS3 Compliant, representing the current RoHS standard. All three parts meet hazardous substance restrictions for electronic components.

Q: What are the operating temperature differences?

A: The 68683-225LF operates from -65°C to 125°C, providing the widest low-temperature range. The BCS-125-L-D-TE operates from -55°C to 125°C. The 2-215307-5 does not specify an operating temperature range. For applications requiring operation below -55°C, the 68683-225LF is the specified choice.
