C9120-00 Equivalent & Substitute Parts

Part Overview

The C9120-00 is a 20-position DIP socket manufactured by Aries Electronics, designed for through-hole mounting applications requiring gold-plated contacts and wire wrap termination. This component belongs to the Edge-Grip™ series and features a 0.3" (7.62mm) row spacing configuration with phosphor bronze contact materials.

The C9120-00 has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this socket configuration.

Substitute Part Grouping Explanation

Substitution eligibility for the C9120-00 is determined by the following critical parameters:

Position Count & Configuration: 20 positions in 2 x 10 DIP arrangement
Pitch Specification: 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) post pitch
Row Spacing: 0.3" (7.62mm) row spacing
Mounting Method: Through-hole mounting with wire wrap termination
Contact Finish - Mating: Gold plating on mating contacts
Mounting Compatibility: Socket must accommodate standard DIP package footprints with matching pitch and row spacing

The substitute part AR 20-HZW/TN meets these core substitution criteria. Both parts share identical position counts, pitch specifications, row spacing, mounting type, and mating contact finish. These parameters ensure mechanical and electrical compatibility at the board level and with standard DIP integrated circuits.

Engineering Selection Recommendations

The AR 20-HZW/TN qualifies as a functional substitute for the obsolete C9120-00 based on matching core electrical and mechanical parameters: identical position count, pitch specifications, row spacing, mounting type, and mating contact finish.

The AR 20-HZW/TN carries active product status from Assmann WSW Components, ensuring ongoing availability and supply chain support. Both parts maintain ROHS3 compliance and UL94 V-0 flammability ratings, satisfying regulatory requirements.

Differences exist in operating temperature range, current rating, contact materials, and frame configuration. The AR 20-HZW/TN supports a higher current rating (3 A versus 1.5 A) and operates within a narrower temperature range (-40°C ~ 105°C versus -55°C ~ 125°C). Contact material differs (beryllium copper versus phosphor bronze), and the AR 20-HZW/TN features an open frame design compared to the closed frame of the C9120-00. These differences do not preclude substitution for standard DIP socket applications but must be evaluated against specific system requirements.

Frequently Asked Questions (FAQ)

Q: What makes AR 20-HZW/TN a suitable substitute for C9120-00?

A: Both parts share identical critical parameters: 20-position DIP configuration, 0.100" (2.54mm) pitch, 0.3" (7.62mm) row spacing, through-hole mounting, wire wrap termination, and gold mating contact finish. These parameters ensure mechanical and electrical compatibility with standard DIP integrated circuits and existing PCB layouts.

Q: Are there any compatibility concerns when substituting AR 20-HZW/TN for C9120-00?

A: The substitute part operates within a narrower temperature range (-40°C ~ 105°C versus -55°C ~ 125°C). Applications requiring operation below -40°C or above 105°C must retain the original C9120-00 specification. The AR 20-HZW/TN features an open frame design versus the closed frame of the C9120-00; this difference does not affect standard DIP package compatibility but may influence mechanical support in specific mounting configurations.

Q: What is the difference in current rating between these parts?

A: The C9120-00 is rated for 1.5 A, while the AR 20-HZW/TN is rated for 3 A. The higher current rating of the substitute part does not create compatibility issues for applications designed for the original 1.5 A specification.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the C9120-00 and AR 20-HZW/TN are ROHS3 compliant and carry UL94 V-0 flammability ratings. Both are classified as REACH unaffected and share the same ECCN and HTSUS codes.

Q: What is the difference in contact material?

A: The C9120-00 uses phosphor bronze contacts, while the AR 20-HZW/TN uses beryllium copper contacts. Both materials are suitable for DIP socket applications. The mating contact finish remains gold in both cases, ensuring consistent electrical performance.

Q: Why is the C9120-00 listed as obsolete?

A: Obsolete status indicates the C9120-00 is no longer manufactured by Aries Electronics. The AR 20-HZW/TN maintains active product status, providing a path to continued supply and support for equivalent socket functionality.
