M20-9701545 Equivalent & Substitute Parts

Part Overview

The Harwin M20-9701545 is a rectangular connector header featuring a right-angle through-hole mount configuration with 30 positions at 2.54mm pitch. This connector is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The M20 series header is designed for board-to-board or cable applications with unshrouded, cuttable construction and solder termination. Active alternatives from Molex, Amphenol ICC (FCI), Preci-Dip, and 3M provide functional equivalence with varying contact finishes and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 30
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole, Right Angle
Termination: Solder
Contact Type: Male Pin
Style: Board to Board or Cable
Shrouding: Unshrouded
Fastening Type: Push-Pull
Material Flammability Rating: UL94 V-0

All substitute parts listed meet these mandatory electrical and mechanical parameters. Variations in contact finish, contact material, insulation material, and operating temperature ranges are secondary considerations that do not prevent functional substitution when these core parameters align.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance)

The Molex C-Grid 71764 series (0717640030, 0717640130, 0717640230) and Amphenol ICC BERGSTIK® II series (77317-112-30LF, 77317-412-30LF, 77317-812-30LF) are active products with ROHS3 compliance or RoHS compliance. These parts maintain the core electrical and mechanical specifications of the M20-9701545 and are recommended for new designs and ongoing procurement.

Secondary Substitutes (Active Status, Compliance Considerations)

The Amphenol ICC BERGSTIK® II part 68021-130 is active with extended operating temperature range (-65°C ~ 125°C) and 3A current rating matching the original part. However, REACH Affected status requires verification for applications subject to REACH regulations. The variant 68021-130H is RoHS non-compliant and should be avoided for applications requiring RoHS compliance.

Tertiary Substitutes (Active Status, Parameter Variations)

The Preci-Dip 802-10-030-20-001101 is ROHS3 compliant and active, with brass contact material and gold finish matching the original part. The 3M 961230-5804-AR is active and RoHS compliant but features a reduced current rating of 2A per contact compared to the 3A specification of the original part, limiting its use to lower-current applications.

Frequently Asked Questions (FAQ)

Q: Can I use a Molex 0717640030 (tin finish) as a direct replacement for the Harwin M20-9701545 (gold finish)?

A: The Molex 0717640030 meets all core electrical and mechanical parameters: 30 positions, 2.54mm pitch, 2 rows, through-hole right-angle mount, solder termination, and push-pull fastening. The contact finish difference (tin vs. gold) does not prevent functional substitution. Contact finish selection depends on application-specific requirements for corrosion resistance and signal integrity.

Q: What is the difference between Amphenol ICC 77317-112-30LF and 77317-812-30LF?

A: Both parts are BERGSTIK® series headers with identical mechanical and electrical specifications. The primary difference is contact finish thickness on the mating surface: 77317-112-30LF has 30.0µin (0.76µm) gold finish, while 77317-812-30LF has 15.0µin (0.38µm) gold finish. Both are RoHS compliant and active products.

Q: Why is the Amphenol ICC 68021-130H listed as RoHS non-compliant?

A: The 68021-130H variant does not meet ROHS3 or RoHS compliance requirements. For applications requiring RoHS compliance, use the compliant variant 68021-130 or select from the Molex, Amphenol BERGSTIK® (77317 series), Preci-Dip, or 3M alternatives listed.

Q: Can I use the 3M 961230-5804-AR in place of the M20-9701545?

A: The 3M 961230-5804-AR meets core mechanical specifications but has a reduced current rating of 2A per contact compared to the original part's 3A rating. Use this part only in applications where the 2A current limit is acceptable.

Q: What packaging options are available for these substitute parts?

A: Molex C-Grid 71764 series parts are supplied in Tube packaging. Amphenol ICC BERGSTIK® series parts are supplied in Bag or Bulk packaging. Preci-Dip 802-10-030-20-001101 is supplied in Bulk packaging. 3M 961230-5804-AR packaging is not specified. Verify packaging requirements with your procurement process.

Q: Are all substitute parts MSL 1 (Unlimited)?

A: Yes, all listed substitute parts have Moisture Sensitivity Level 1 (Unlimited), matching the original M20-9701545 specification.
