C9118-00 Equivalent & Substitute Parts

Part Overview

The C9118-00 is an 18-position DIP socket manufactured by Aries Electronics, designed for IC and transistor applications with 0.3" (7.62mm) row spacing. This component features gold-plated phosphor bronze contacts, wire wrap termination, and a closed frame design suitable for through-hole mounting. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the C9118-00 is determined by the following critical parameters:

• DIP Socket Type with 0.3" (7.62mm) Row Spacing: The substitute must maintain the same row spacing to ensure mechanical compatibility with existing PCB layouts and component footprints.
• Pitch - Mating (0.100" / 2.54mm): Contact spacing must be identical for proper IC pin alignment.
• Through Hole Mounting: The substitute must support through-hole PCB assembly methods.
• Wire Wrap Termination: Post configuration must accommodate wire wrap connection techniques.
• Gold Contact Finish: Mating surface contact finish specification for electrical performance and reliability.
• Operating Temperature Range: The substitute must support the required thermal operating window.
• Current Rating: The substitute must meet or exceed the current-carrying capacity requirements.
• RoHS Compliance: Regulatory compliance status must be maintained.

The AR 20-HZW/TN from Assmann WSW Components is identified as a substitute part. While this part differs in position count (20 vs. 18), it maintains the critical mechanical and electrical parameters that define DIP socket compatibility within this product category.

Engineering Selection Recommendations

The AR 20-HZW/TN qualifies as a substitute based on maintained compliance with ROHS3 and UL94 V-0 flammability standards. The substitute part is currently in active production status, ensuring ongoing availability compared to the obsolete C9118-00.

Key considerations for selection:

• The AR 20-HZW/TN provides higher current rating (3 A vs. 1.5 A), offering improved electrical capacity.
• The operating temperature range of the substitute (-40°C ~ 105°C) is narrower than the main part (-55°C ~ 125°C). Applications requiring operation below -40°C or above 105°C must account for this limitation.
• The increased position count (20 vs. 18) requires verification that the PCB footprint and application circuit can accommodate the additional pins or that unused positions are acceptable for the intended design.
• Contact material differs (Beryllium Copper vs. Phosphor Bronze), with both materials suitable for gold-plated mating surfaces and wire wrap termination.

Frequently Asked Questions (FAQ)

Q: Can the AR 20-HZW/TN directly replace the C9118-00 in existing designs?

A: Direct replacement requires PCB layout verification. The AR 20-HZW/TN has 20 positions versus 18 for the C9118-00. If the PCB footprint accommodates only 18 positions, physical installation is not possible. If the PCB supports 20 positions or the extra positions can remain unpopulated, mechanical and electrical compatibility is maintained through the matching 0.3" row spacing and 0.100" mating pitch.

Q: What is the impact of the narrower operating temperature range on the substitute part?

A: The AR 20-HZW/TN operates from -40°C to 105°C, compared to the C9118-00 range of -55°C to 125°C. Applications requiring operation at temperatures below -40°C or above 105°C cannot use this substitute without thermal performance verification.

Q: Are the contact materials interchangeable?

A: Both Phosphor Bronze (C9118-00) and Beryllium Copper (AR 20-HZW/TN) are standard contact materials for DIP sockets with gold plating. Both materials provide suitable electrical conductivity and contact reliability for wire wrap termination applications.

Q: Does the higher current rating of the substitute part affect compatibility?

A: The AR 20-HZW/TN current rating of 3 A exceeds the C9118-00 specification of 1.5 A. This represents improved electrical capacity and does not create compatibility issues for applications designed for 1.5 A operation.

Q: What packaging differences exist between these parts?

A: The C9118-00 packaging is not specified in available data. The AR 20-HZW/TN is supplied in tube packaging. Packaging format may affect handling, storage, and assembly processes but does not impact electrical or mechanical compatibility.
