C&K 7101J2CGI2 Rocker Switch SPDT 5A 120V – Equivalent & Substitute Parts

Part Overview

The C&K 7101J2CGI2 is a through-hole mounted rocker switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A AC/DC at 120V AC and 28V DC. The switch features a black paddle actuator, epoxy potting, and PC pin termination. This part is currently active in production with 1,110 units in stock.

Equivalent and substitute parts are necessary when the original part becomes unavailable, when alternative mounting configurations are required, or when design flexibility permits selection from compatible alternatives within the same electrical and mechanical parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101J2CGI2 is determined by the following critical parameters:

• Circuit Configuration: SPDT (Single Pole Double Throw)
• Switch Function: On-On operation
• Current Rating: Minimum 5A AC capability
• Voltage Rating – AC: Minimum 120V
• Voltage Rating – DC: Minimum 28V
• Actuator Type: Paddle
• Termination Style: PC Pin
• Operating Temperature Range: –30°C to +85°C minimum
• RoHS Compliance: ROHS3 Compliant

The substitute parts listed below meet or exceed these electrical parameters. Differences in mounting type (panel mount versus through hole), actuator color, mechanical life, and product status are noted but do not preclude functional equivalence in applications where the mounting configuration can be accommodated.

Engineering Selection Recommendations

Primary Selection – 7101J2CGI2 (C&K)

The 7101J2CGI2 remains the recommended choice for new designs and ongoing production. This part is active in production, carries full ROHS3 compliance, holds cULus approval, and demonstrates superior electrical life (100,000 cycles). Through-hole mounting is standard for PCB integration. Current inventory of 1,110 units supports immediate availability.

Substitute Selection – M2012TNW03 Series (NKK Switches)

The NKK M2012TNW03 series (variants EA, EC, EG) provides electrical equivalence with the following considerations:

• All three variants exceed the AC voltage and current requirements of the 7101J2CGI2 (125V AC, 6A AC versus 120V AC, 5A AC).
• DC current rating is reduced to 4A (versus 5A on the original part); DC voltage rating is increased to 30V (versus 28V).
• Panel mount, flange configuration differs from through-hole mounting; mechanical integration requires adapter or redesign.
• Product status is obsolete; long-term availability is not assured.
• Electrical life is reduced to 25,000 cycles (versus 100,000 cycles on the original part).
• CSA and UL approvals are provided; REACH status differs (unaffected versus affected on the original part).

Substitution with the M2012TNW03 series is permissible only when mounting configuration can be accommodated and reduced electrical life is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can the M2012TNW03 series directly replace the 7101J2CGI2 in existing designs?

A: Electrical substitution is possible based on circuit configuration (SPDT), switch function (On-On), and voltage/current ratings. However, mounting type differs: the 7101J2CGI2 is through-hole, while the M2012TNW03 series is panel mount with flange. PCB layout and mechanical integration must be evaluated before substitution.

Q: What is the impact of reduced electrical life on the M2012TNW03 series?

A: The M2012TNW03 series is rated for 25,000 electrical cycles, compared to 100,000 cycles for the 7101J2CGI2. Applications requiring frequent switching or extended operational life should retain the original part. Low-cycle-count applications may tolerate the reduced rating.

Q: Are all three M2012TNW03 variants (EA, EC, EG) electrically equivalent?

A: Yes. Variants EA, EC, and EG differ only in actuator color (black, red, and blue respectively). All three share identical electrical specifications, voltage ratings, current ratings, and termination style. Selection among variants is based on visual identification requirements only.

Q: What is the significance of product status differences?

A: The 7101J2CGI2 is active in production with assured long-term availability. The M2012TNW03 series is obsolete, indicating discontinued production. Obsolete parts carry risk of future unavailability and should be used only when the active part cannot meet design requirements.

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

A: The 7101J2CGI2 carries cULus approval. The M2012TNW03 series carries CSA and UL approvals. Both are ROHS3 compliant. REACH status differs: the 7101J2CGI2 is REACH affected; the M2012TNW03 series is REACH unaffected. Regulatory requirements for the target application must be verified.
