52601-G26-6 Equivalent & Substitute Parts

Part Overview

The 52601-G26-6 is a rectangular connector header manufactured by Amphenol ICC (FCI) in the Quickie™ series. This through-hole connector features 26 positions arranged in 2 rows with 0.100" (2.54mm) pitch, designed for board-to-board or cable applications. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the 52601-G26-6 is determined by strict equivalence across the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (26)
Number of rows (2)
Mating pitch (0.100" / 2.54mm)
Row spacing (0.100" / 2.54mm)
Mounting type (Through Hole)
Termination method (Solder)
Shrouding configuration (Shrouded - 4 Wall)
Contact shape (Square)
Flammability rating (UL94 V-0)
Insulation color (Black)

All three substitute parts meet these core requirements. Variations in contact length, insulation height, contact finish thickness, and insulation material composition do not prevent functional substitution in applications designed for the 52601-G26-6.

Engineering Selection Recommendations

The 52601-G26-6 is obsolete and no longer in active production. All three substitute parts are active products with current manufacturing support.

For applications requiring RoHS3 compliance, the Molex 0702462601 and 3M N2526-6002-RB are preferred selections. The Molex part maintains the same insulation height (0.365") as the original and is available in high volume (1372 pcs in stock). The 3M part offers the highest inventory availability (38359 pcs) and includes specified operating temperature range (-55°C ~ 105°C) and current rating (1.75A).

The JAE Electronics PS-26PE-D4T1-B1E is RoHS compliant and provides an alternative with different fastening type (Latch Holder versus Push-Pull). This part has lower inventory availability (848 pcs).

All substitute parts share identical core electrical and mechanical interfaces with the original 52601-G26-6, ensuring pin-for-pin compatibility in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0702462601 be used as a direct replacement for the 52601-G26-6?

A: Yes. Both connectors share identical mating pitch (0.100"), row spacing (0.100"), number of positions (26), mounting type (through hole), and shrouding configuration (4-wall). The Molex part is active and RoHS3 compliant, making it suitable for new designs and legacy board retrofits.

Q: What is the difference between the 3M N2526-6002-RB and the Molex 0702462601?

A: Both are functionally equivalent for the 52601-G26-6 application. The 3M part offers higher inventory availability and includes specified operating temperature (-55°C ~ 105°C) and current rating (1.75A). The Molex part maintains identical insulation height to the original connector. Contact material differs (Copper Alloy for 3M versus Phosphor Bronze for Molex), but both are acceptable for standard applications.

Q: Why does the JAE Electronics PS-26PE-D4T1-B1E have a different fastening type?

A: The JAE part uses Latch Holder fastening instead of Push-Pull. This is a mechanical interface difference that may affect mating connector compatibility. Verify that mating connectors support Latch Holder fastening before selecting this substitute.

Q: Are all substitute parts RoHS compliant?

A: The Molex 0702462601 and 3M N2526-6002-RB are ROHS3 compliant. The JAE Electronics PS-26PE-D4T1-B1E is RoHS compliant. The original 52601-G26-6 is RoHS non-compliant. For applications requiring RoHS compliance, use one of the three substitute parts.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching connector type (Header), contact type (Male Pin), number of positions (26), number of rows (2), mating pitch (0.100"), row spacing (0.100"), mounting type (Through Hole), termination (Solder), shrouding (Shrouded - 4 Wall), contact shape (Square), and flammability rating (UL94 V-0). All three substitute parts meet these criteria.

Q: Can contact length variations affect PCB compatibility?

A: Contact length variations are within acceptable tolerances for standard PCB designs. The mating contact lengths range from 0.230" to 0.243", and post lengths range from 0.110" to 0.150". Verify specific PCB pad depth and solder joint requirements for your application if using parts with significantly different post lengths.
