3M 7064-60B3TH 64-Position DIN Connector Header Equivalent & Substitute Parts

Part Overview

The 3M 7064-60B3TH is a 64-position DIN connector header with male pins, gold contact finish, and through-hole solder termination. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance, repairs, and new designs requiring compatible backplane connector solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 7064-60B3TH is determined by the following critical parameters:

• Connector Configuration: 64 positions, 2 rows, 0.100" (2.54mm) pitch, DIN standard header format with male pins
• Mounting and Termination: Through-hole solder termination (primary requirement); panel mount variants are not direct substitutes for PCB-mounted applications
• Electrical Performance: Current rating and operating temperature range must meet or exceed application requirements
• Contact Finish: Gold or gold-palladium finishes are acceptable for equivalent electrical performance
• Compliance: RoHS3 compliance preferred for new designs; RoHS non-compliant parts acceptable for legacy system maintenance

Three substitute parts meet these criteria with varying compliance and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

HARTING 09723646902 is the primary substitute for direct PCB-mounted through-hole applications. It maintains the same 64-position, 2-row, 0.100" pitch configuration with identical operating temperature range (-55°C ~ 125°C) and UL94 V-0 flammability rating. The gold-palladium contact finish provides equivalent electrical performance to the original gold finish. ROHS3 compliance makes this part suitable for new designs and legacy system replacements. Current rating of 2A is lower than the original 3A specification; applications requiring 3A current capacity must be evaluated for compatibility.

Hirose PCN10-64P-2.54DSA(72) is an alternative for applications with operating temperature requirements not exceeding 85°C. This part maintains the 64-position, 2-row configuration with gold contact finish and ROHS3 compliance. The Style B designation indicates a different mechanical profile compared to the original Style Q. Current rating of 2A applies the same limitation as the HARTING substitute. This part is suitable for legacy system maintenance where temperature range reduction is acceptable.

HARTING 09721646902 is not recommended as a direct substitute due to panel mount configuration, which is incompatible with PCB-mounted through-hole applications requiring direct solder termination to the board.

Frequently Asked Questions (FAQ)

Q: Can HARTING 09723646902 be used as a direct replacement for 3M 7064-60B3TH in existing PCB designs?

A: Yes, for applications where current requirements do not exceed 2A. The 64-position, 2-row, 0.100" pitch configuration, through-hole solder termination, and identical operating temperature range (-55°C ~ 125°C) ensure mechanical and electrical compatibility. The gold-palladium contact finish is functionally equivalent to gold for signal integrity and reliability.

Q: What is the difference between Style Q and Style B connectors?

A: Style designation indicates mechanical profile and keying features specific to DIN 41612 standards. Style Q and Style B have different physical dimensions and keying arrangements. Substitution between styles requires mechanical compatibility verification with mating connectors and PCB layout.

Q: Why is the current rating lower on substitute parts compared to the original 3M part?

A: The HARTING 09723646902 and Hirose PCN10-64P-2.54DSA(72) are rated at 2A versus the original 3A specification. This reflects design differences in contact geometry and material composition. Applications requiring 3A current capacity must be evaluated to determine if 2A rating is acceptable or if alternative parts with higher current ratings are necessary.

Q: Is HARTING 09721646902 suitable for PCB-mounted applications?

A: No. HARTING 09721646902 is configured for panel mount installation, which is mechanically incompatible with PCB-mounted through-hole applications. This part is not a direct substitute for the 3M 7064-60B3TH.

Q: What are the RoHS compliance implications for substitute part selection?

A: The original 3M 7064-60B3TH is RoHS non-compliant. All three substitute parts are ROHS3 compliant, making them suitable for new designs and systems requiring RoHS compliance. For legacy system maintenance where RoHS compliance is not a requirement, any of the three parts may be considered based on other electrical and mechanical parameters.

Q: Does operating temperature range affect substitute part selection?

A: Yes. The Hirose PCN10-64P-2.54DSA(72) has a reduced operating temperature range of -55°C ~ 85°C compared to the original -55°C ~ 125°C specification. Applications requiring operation above 85°C must use HARTING 09723646902, which maintains the full -55°C ~ 125°C range.
