CP2-HC055-GA1-FJ Equivalent & Substitute Parts

Part Overview

The CP2-HC055-GA1-FJ is a 77-position backplane connector header manufactured by 3M, part of the MetPak™ CP2 series. This press-fit connector features 55 signal positions plus 22 ground positions with 0.079" (2.00mm) pitch and is designed for CompactPCI applications. The connector is currently active in production with full position loading and gold-plated contacts rated for -55°C to 125°C operation. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component sourcing, inventory management, or design flexibility.

Substitute Part Grouping Explanation

The substitute parts identified for CP2-HC055-GA1-FJ are HARTING har-bus® HM series connectors: 17030551201, 17030552201, and 17030552202. These substitutes are qualified based on the following critical parameters that determine functional equivalence:

Matching Parameters:

• Connector Type: Header, Male Pins
• Pitch: 0.079" (2.00mm)
• Number of Rows: 5
• Mounting Type: Through Hole
• Termination: Press-Fit
• Connector Style: C 11
• Operating Temperature: -55°C ~ 125°C
• Features: Board Guide
• Contact Finish: Gold or Gold-Palladium
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Position Configuration Note: The substitute parts are 55-position connectors without the additional 22 ground positions present in the main part. Substitution is valid when the application requires 55 signal positions with equivalent electrical and mechanical characteristics. The HARTING parts maintain identical pitch, row configuration, mounting method, and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and meet or exceed the compliance requirements of the main part. The HARTING har-bus® HM series connectors (17030551201, 17030552201, 17030552202) are ROHS3 compliant, exceeding the RoHS compliance level of the 3M CP2-HC055-GA1-FJ. All parts share identical electrical and mechanical specifications for pitch, mounting type, termination method, connector style, and operating temperature range.

The primary distinction between the main part and substitutes is the position count: the CP2-HC055-GA1-FJ provides 77 positions (55 signal + 22 ground), while the HARTING alternatives provide 55 positions. Selection between substitute parts should be based on application requirements for ground pin distribution and available inventory levels.

Frequently Asked Questions (FAQ)

Q: Can HARTING 17030551201, 17030552201, or 17030552202 directly replace the 3M CP2-HC055-GA1-FJ?

A: Direct replacement is valid when the application requires 55-position connector functionality with 0.079" (2.00mm) pitch, press-fit termination, and -55°C to 125°C operating range. The HARTING parts match these specifications. However, the main part includes 22 additional ground positions; applications requiring this ground pin distribution must retain the original part.

Q: What are the differences between the three HARTING substitute parts?

A: All three HARTING parts (17030551201, 17030552201, 17030552202) share identical electrical and mechanical specifications. Differences are limited to packaging (all supplied in Tube) and connector usage designation. Part 17030552201 specifies Backplane connector usage, while 17030551201 and 17030552202 do not specify usage. All three are functionally equivalent for 55-position header applications.

Q: Are there compliance or certification differences between the main part and substitutes?

A: The main part is RoHS Compliant. The HARTING substitutes are ROHS3 Compliant, representing a higher compliance standard. All parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The HARTING parts include REACH Unaffected status, which is not specified for the main part.

Q: What is the significance of the position count difference?

A: The CP2-HC055-GA1-FJ provides 77 total positions configured as 55 signal positions plus 22 dedicated ground positions across 5 + 2 rows. The HARTING substitutes provide 55 positions across 5 rows. Applications requiring the specific ground pin distribution of the main part cannot use the 55-position substitutes. Applications requiring only 55 signal positions can use the HARTING alternatives.

Q: Are the contact finish specifications compatible?

A: The main part specifies gold contact finish at 10.0µin (0.25µm) thickness. The HARTING substitutes specify gold or gold-palladium contact finish without thickness specification. Both finishes are compatible for press-fit termination and provide equivalent electrical performance in the specified operating temperature range.
