Substitute Part Grouping Explanation

The HR25-9TP-20SC has one direct substitute within the HR25 series: HR25-9TP-20SC(72). Substitution eligibility is determined by the following critical parameters:

• Series Compatibility: Both parts belong to the HR25 series
• Connector Type: Both are plug housings for female sockets
• Position Count: Identical 20-position configuration
• Shell Size: Matching shell size 9 insert
• Mounting Configuration: Both are free-hanging, in-line designs
• Fastening Method: Both use threaded fastening with keyed orientation
• Shell Construction: Identical zinc alloy with nickel finish
• Shielding: Both are shielded designs
• Temperature Range: Identical operating temperature specification (-25°C ~ 85°C)
• Flammability Rating: Both meet UL94 V-0 standard

The primary distinction between these parts is packaging format and product status, not electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

HR25-9TP-20SC(72) is the direct substitute for HR25-9TP-20SC. Both parts are mechanically and electrically identical across all functional parameters. Selection between these parts should be based on the following criteria:

Use HR25-9TP-20SC(72) when:

• New designs require RoHS compliance
• Long-term supply chain stability is required (active product status)
• Bulk packaging format aligns with procurement requirements

Use HR25-9TP-20SC when:

• Existing inventory of the obsolete variant is available
• RoHS compliance is not a system requirement
• Retrofit applications require exact part number matching

Both parts maintain identical electrical performance, mechanical fit, and thermal characteristics. The HR25-9TP-20SC(72) variant offers improved regulatory compliance and active manufacturer support.

Frequently Asked Questions (FAQ)

Q: Are HR25-9TP-20SC and HR25-9TP-20SC(72) mechanically interchangeable?

A: Yes. Both parts share identical shell size (9), position count (20), mounting configuration (free-hanging in-line), fastening method (threaded), and all mechanical features including backshell, cable clamp, coupling nut, and strain relief.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (obsolete vs. active), RoHS compliance status, and packaging format (standard vs. bulk). All electrical and mechanical specifications are identical.

Q: Can HR25-9TP-20SC(72) be used in applications originally designed for HR25-9TP-20SC?

A: Yes. The HR25-9TP-20SC(72) is a direct functional equivalent. The improved RoHS compliance of the (72) variant makes it suitable for all applications where the original part was specified.

Q: What does the "(72)" designation indicate?

A: The (72) suffix indicates the bulk packaging variant of the same connector. This designation does not affect electrical or mechanical performance.

Q: Are there any temperature or environmental limitations when substituting these parts?

A: No. Both parts operate across the identical temperature range (-25°C ~ 85°C) and maintain the same moisture sensitivity level (MSL 1 - Unlimited). Environmental performance is equivalent.

Q: What is the contact configuration for these connectors?

A: Both parts use crimp-type contacts in a 20-position circular arrangement. Contacts are not included with the housing and must be sourced separately.
