EG1260ASR Equivalent & Substitute Parts

Part Overview

The EG1260ASR is a slide switch SPDT (Single Pole Double Throw) surface mount component manufactured by E-Switch. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The EG1260ASR operates at 300mA DC with a 4V rating and features a right-angle gull wing termination suitable for surface mount applications. Substitute parts must maintain electrical and mechanical compatibility across the specified parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the EG1260ASR are qualified based on the following electrical and mechanical parameters:

Circuit configuration: SPDT
Current rating: 300mA (DC)
Voltage rating: 4V DC
Mounting type: Surface Mount, Right Angle
Termination style: Gull Wing
Actuator length: 1.50mm
Switch travel: 1.50mm
Electrical life: 10,000 Cycles minimum
RoHS3 compliance
MSL rating: 1 (Unlimited)

All qualified substitutes maintain these core parameters. Variations in contact timing, contact finish, actuator material, and operating force do not preclude substitution when all primary electrical and mechanical specifications align.

Engineering Selection Recommendations

EG1260ASQ is the manufacturer-recommended direct substitute from E-Switch. This part maintains identical electrical and mechanical specifications while offering active product status and higher inventory availability (1073 units in stock versus 654 units for the obsolete EG1260ASR).

CUS-12TB from Nidec Components Corporation qualifies as a functional equivalent with the highest inventory availability (31,870 units). This part maintains all critical electrical parameters and mounting specifications. The contact finish differs (gold versus silver), and contact timing is non-shorting (BBM) rather than shorting (MBB). Operating force is specified at 204gf compared to 150gf for the main part.

SK-12C0405-SG 1.5 RT from C&K qualifies as a functional equivalent with active product status and 5,322 units in stock. This part maintains all critical electrical parameters and mounting specifications. Operating temperature range is not specified in available documentation. Operating force matches the main part at 150gf.

All three substitute parts carry ROHS3 compliance, MSL rating 1 (Unlimited), and REACH Unaffected status, matching the regulatory profile of the EG1260ASR.

Frequently Asked Questions (FAQ)

Q: Can EG1260ASQ be used as a direct replacement for EG1260ASR?

A: Yes. EG1260ASQ is the manufacturer-recommended substitute from E-Switch and maintains identical specifications across all critical electrical and mechanical parameters, including circuit configuration, current rating, voltage rating, mounting type, termination style, actuator dimensions, and operating temperature range.

Q: What are the key differences between CUS-12TB and the EG1260ASR?

A: CUS-12TB maintains all critical electrical and mechanical specifications. Differences include contact finish (gold versus silver), contact timing (non-shorting BBM versus shorting MBB), and operating force (204gf versus 150gf). These differences do not affect substitution eligibility based on the specified parameter criteria.

Q: Is SK-12C0405-SG 1.5 RT compatible with EG1260ASR applications?

A: Yes. SK-12C0405-SG 1.5 RT maintains all critical electrical and mechanical specifications including circuit configuration, current rating, voltage rating, mounting type, termination style, and switch travel. Operating temperature range is not specified in available documentation for this part.

Q: What packaging options are available for substitute parts?

A: EG1260ASQ is available in standard packaging. CUS-12TB is available in Cut Tape (CT) and Digi-Reel packaging. SK-12C0405-SG 1.5 RT is available in Tape & Reel (TR) packaging.
