Engineering Selection Recommendations

The 52601-G26-4 is obsolete; therefore, active alternatives are required for new designs and ongoing procurement.

52601-G26-4LF is the direct successor from Amphenol ICC (FCI) in the same Quickie™ series. This part maintains identical mechanical and electrical specifications to the original while achieving RoHS compliance. The primary difference is the addition of tin finish on the post contacts. This part is recommended for applications requiring continuity with the original Amphenol ICC design ecosystem.

0702462601 and 0702462604 are Molex C-Grid 70246 series alternatives. Both parts are ROHS3 compliant and feature glass-filled PBT insulation material, providing enhanced mechanical stability compared to the thermoplastic insulation of the original. Contact length variations (mating and post) are minor and remain within acceptable tolerance ranges for standard board-to-cable applications. The 0702462604 variant offers higher inventory availability in tray packaging.

PS-26PE-D4T1-B1E is a JAE Electronics alternative featuring a latch holder fastening mechanism instead of push-pull. This part maintains core dimensional and electrical compatibility while offering an alternative retention method. The insulation height is 0.350" (8.89mm) compared to 0.365" (9.27mm) in other alternatives, representing a minor dimensional variation.

All substitute parts maintain UL94 V-0 flammability rating and keying slot features. Selection should be based on design requirements for fastening type, packaging format, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can 52601-G26-4LF be used as a direct replacement for 52601-G26-4?

A: Yes. The 52601-G26-4LF maintains identical connector type, position count, pitch, shrouding, and mounting specifications. The primary difference is RoHS compliance status and tin finish on post contacts. Mechanical and electrical compatibility is maintained.

Q: What are the key differences between Amphenol ICC and Molex alternatives?

A: Amphenol ICC (52601-G26-4LF) maintains the original Quickie™ series design with thermoplastic insulation. Molex alternatives (0702462601, 0702462604) use glass-filled PBT insulation, offering improved mechanical properties. Contact length dimensions vary slightly but remain compatible with standard board-to-cable applications.

Q: Does the JAE Electronics PS-26PE-D4T1-B1E have different fastening?

A: Yes. The PS-26PE-D4T1-B1E uses a latch holder fastening mechanism, whereas the original 52601-G26-4 and most alternatives use push-pull fastening. This affects mating and unmating force characteristics but maintains positional and electrical compatibility.

Q: Are all substitute parts RoHS compliant?

A: The original 52601-G26-4 is RoHS non-compliant. All active substitute parts listed (52601-G26-4LF, 0702462601, 0702462604, PS-26PE-D4T1-B1E) are RoHS compliant or ROHS3 compliant, meeting current regulatory requirements.

Q: What packaging options are available?

A: 52601-G26-4LF and 0702462604 are supplied in tray packaging. 52601-G26-4, 0702462601, and PS-26PE-D4T1-B1E are supplied in bulk packaging. Selection depends on assembly process requirements and inventory management practices.

Q: Are contact length variations significant?

A: Contact length variations between alternatives are minor (0.230" to 0.240" for mating contacts; 0.110" to 0.135" for post contacts). These variations remain within acceptable tolerances for standard through-hole board-to-cable applications and do not affect mechanical compatibility.
