Substitute Part Grouping Explanation

Substitution eligibility for the 68656-136HLF is determined by strict alignment with the following core parameters: 36-position count, 0.100" (2.54mm) mating pitch, single-row configuration, male pin contact type, through-hole mounting, solder termination, unshrouded design, and square contact geometry. All identified substitutes maintain these electrical and mechanical specifications.

The substitute parts are grouped into two functional categories based on contact length and post geometry:

Category A (Shorter Post Length): 929705-06-36-I, PBC36SFAN, and PEC36SFAN feature reduced overall contact lengths (0.538" to 1.128") suitable for applications with space constraints.

Category B (Extended Post Length): PEC36SFCN provides an extended post length of 0.320" (8.13mm), resulting in an overall contact length of 0.738" (18.75mm), accommodating deeper board penetration requirements.

Engineering Selection Recommendations

All substitute parts maintain active product status and comply with UL94 V-0 flammability requirements and REACH regulations. Selection between substitutes depends on specific application requirements:

929705-06-36-I (3M): Suitable for applications requiring RoHS compliance with gold-plated mating contacts. Operating temperature range of -40°C to 105°C and 2.5A current rating accommodate standard industrial environments.

PBC36SFAN (Sullins): Offers ROHS3 compliance with extended operating temperature range (-65°C to 125°C) and 3A current rating. Shorter post length (0.120") minimizes board penetration depth. Gold-plated mating contacts with tin-plated posts provide corrosion resistance.

PEC36SFAN (Sullins): Provides ROHS3 compliance with tin-plated mating and post contacts, extended operating temperature range (-65°C to 125°C), and 3A current rating. Identical post length to PBC36SFAN with thicker tin plating (100.0µin) on mating surface.

PEC36SFCN (Sullins): Delivers ROHS3 compliance with extended post length (0.320") for deeper board penetration. Tin-plated contacts throughout with -65°C to 125°C operating range and 3A current rating. Suitable for applications requiring increased mechanical engagement.

Frequently Asked Questions (FAQ)

Q: Can the 68656-136HLF be directly replaced with any of these substitutes?

A: All substitute parts maintain the core electrical and mechanical specifications: 36 positions, 0.100" (2.54mm) pitch, single-row configuration, male pin contacts, through-hole solder termination, and unshrouded design. Direct replacement is feasible; however, variations in contact length and post geometry require board layout verification.

Q: What is the primary difference between the substitute parts?

A: The main differentiator is overall contact length and post geometry. The 929705-06-36-I and PBC36SFAN/PEC36SFAN variants feature shorter posts (0.120" to 0.710"), while PEC36SFCN provides an extended post length of 0.320". Contact finish differs between gold-plated (929705-06-36-I, PBC36SFAN) and tin-plated (PEC36SFAN, PEC36SFCN) options.

Q: Are all substitutes RoHS compliant?

A: The 929705-06-36-I is RoHS Compliant. The Sullins parts (PBC36SFAN, PEC36SFAN, PEC36SFCN) are ROHS3 Compliant, representing the current RoHS directive standard.

Q: Which substitute offers the widest operating temperature range?

A: PBC36SFAN, PEC36SFAN, and PEC36SFCN all provide -65°C to 125°C operating temperature range, compared to 929705-06-36-I at -40°C to 105°C.

Q: What contact finish options are available?

A: Gold-plated mating contacts are available on 929705-06-36-I (10.0µin thickness) and PBC36SFAN (10.0µin thickness). Tin-plated mating contacts with thicker plating (100.0µin) are available on PEC36SFAN and PEC36SFCN.

Q: How do the current ratings compare?

A: The 929705-06-36-I supports 2.5A, while PBC36SFAN, PEC36SFAN, and PEC36SFCN all support 3A current rating.

Q: Which substitute is recommended for space-constrained applications?

A: PBC36SFAN and PEC36SFAN feature the shortest overall contact length at 0.538" (13.67mm), making them suitable for applications with limited board depth. PEC36SFCN provides an intermediate option at 0.738" (18.75mm).
