E103J1ALE2 Equivalent & Substitute Parts

Part Overview

The E103J1ALE2 is a rocker switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) configuration with 7.5A AC/DC rating at 125V AC and 28V DC. This through-hole, right-angle mounted switch is designed for on-off-on applications with a sealed, flux-protected design. The product is currently obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and redesign applications where continued functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the E103J1ALE2 are identified based on strict electrical and mechanical parameter compatibility. The primary substitution criteria are:

Critical Parameters for Substitution:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Current rating (7.5A AC/DC minimum)
• Voltage ratings (125V AC / 28V DC minimum)
• Mounting type (Through Hole, Right Angle)
• Actuator type and color (Concave, Black)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)

Substitute parts are grouped into two categories:

Direct Equivalent: Parts that maintain identical electrical specifications and mechanical form factor, differing only in product status or compliance documentation.

Similar Equivalent: Parts that maintain core electrical functionality and mechanical compatibility but with minor parameter variations that remain within acceptable operating ranges for the application.

Engineering Selection Recommendations

E103J1ARE2 (Direct Equivalent - Recommended Primary Choice)

The E103J1ARE2 is the direct equivalent to the obsolete E103J1ALE2. Both parts are manufactured by C&K and maintain identical electrical specifications (7.5A AC/DC, 125V AC, 28V DC), mechanical configuration (Through Hole, Right Angle), and functional characteristics (SPDT, On-Off-On). The E103J1ARE2 is currently in active production status with 691 units in stock. Both parts carry cULus approval and ROHS3 compliance. The primary difference is product status: E103J1ARE2 is active and represents the direct replacement path for the obsolete E103J1ALE2.

300SP3J1BLKM6QE (Similar Equivalent - Secondary Option)

The 300SP3J1BLKM6QE, manufactured by E-Switch, provides functional substitution with the following considerations: Current rating is 5A AC/DC (versus 7.5A), and AC voltage rating is 120V (versus 125V). DC voltage rating remains 28V. All other parameters—circuit configuration (SPDT), switch function (On-Off-On), mounting type (Through Hole, Right Angle), actuator specifications, termination style, operating temperature range, and electrical life—are maintained. This part is active in production with 882 units in stock and carries ROHS3 compliance. Selection of this part requires confirmation that the application current and voltage requirements do not exceed 5A and 120V AC respectively.

Frequently Asked Questions (FAQ)

Q: Can E103J1ARE2 be used as a direct replacement for E103J1ALE2?

A: Yes. The E103J1ARE2 is the direct equivalent. Both parts share identical electrical ratings (7.5A AC/DC, 125V AC, 28V DC), circuit configuration (SPDT), switch function (On-Off-On), mounting type (Through Hole, Right Angle), and mechanical specifications. The E103J1ARE2 is currently in active production, making it the recommended replacement for the obsolete E103J1ALE2.

Q: What are the limitations of using 300SP3J1BLKM6QE as a substitute?

A: The 300SP3J1BLKM6QE has reduced current and voltage ratings: 5A AC/DC (versus 7.5A) and 120V AC (versus 125V AC). DC voltage rating remains at 28V. This part is suitable only for applications where the circuit current does not exceed 5A and AC voltage does not exceed 120V. All other functional and mechanical parameters are compatible.

Q: Are there any compliance or certification differences between the substitute parts?

A: E103J1ALE2 and E103J1ARE2 both carry cULus approval and ROHS3 compliance. The 300SP3J1BLKM6QE carries ROHS3 compliance but does not specify an approval agency. Applications requiring specific regulatory certifications should prioritize E103J1ARE2.

Q: What is the difference between "Direct Equivalent" and "Similar Equivalent"?

A: Direct Equivalent (E103J1ARE2) maintains all electrical and mechanical specifications identical to the original part. Similar Equivalent (300SP3J1BLKM6QE) maintains core functionality and mechanical compatibility but with reduced current and voltage ratings. Direct equivalents are preferred when available; similar equivalents require application-specific verification.

Q: Can these parts be used interchangeably in all applications?

A: E103J1ARE2 can be used interchangeably with E103J1ALE2 in all applications. The 300SP3J1BLKM6QE can be used only in applications where circuit current does not exceed 5A and AC voltage does not exceed 120V. Verify application requirements before selection.

Q: What is the packaging difference between these parts?

A: E103J1ALE2 and E103J1ARE2 packaging is not specified in available documentation. The 300SP3J1BLKM6QE is supplied in bulk packaging. Contact the manufacturer for specific packaging requirements.
