Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1101M2S2V3LE2 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (minimum 6A AC/DC or equivalent)
• Voltage ratings (minimum 120V AC, 28V DC)
• Mounting type (through hole preferred for direct replacement)
• Termination style (PC Pin)
• Operating temperature range overlap

Substitution Categories:

Direct Substitute (Identical Electrical and Mechanical Specifications): The 1101M2S2V3RE2 from C&K maintains all critical electrical parameters and mounting characteristics, differing only in product status (active vs. obsolete) and minor feature variations.

Similar Substitute (Compatible Electrical Performance with Mounting Variation): The 48ASSP1S1V2QAT from Grayhill Inc. provides equivalent SPDT switching functionality with comparable current and voltage ratings. This part operates at slightly higher specifications in certain parameters and uses panel mount configuration instead of through-hole mounting.

Engineering Selection Recommendations

For Direct Replacement (Recommended Primary Option): The C&K 1101M2S2V3RE2 is the preferred substitute. This part maintains identical electrical specifications, mounting configuration, and termination style as the obsolete 1101M2S2V3LE2. The transition from obsolete to active product status ensures continued availability and supply chain stability. Both parts comply with RoHS requirements and share equivalent environmental ratings.

For Alternative Applications (Secondary Option): The Grayhill Inc. 48ASSP1S1V2QAT provides functional SPDT switching capability with active product status. This substitute is suitable for applications where panel mount configuration is acceptable. The 5A current rating remains adequate for most applications requiring 6A nominal capacity, provided actual circuit current does not exceed 5A. The extended operating temperature range (-30°C to 85°C) offers improved thermal performance compared to the original specification. Electrical life of 30,000 cycles is lower than the original 40,000 cycles and should be evaluated against application duty cycle requirements.

Compliance Considerations: All substitute parts maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component. MSL rating of 1 (unlimited) across all options eliminates moisture sensitivity concerns for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the 1101M2S2V3RE2 be used as a direct drop-in replacement for the 1101M2S2V3LE2? A: Yes. The 1101M2S2V3RE2 maintains identical electrical ratings (6A at 120V AC, 28V DC), circuit configuration (SPDT), switch function (On-On), mounting type (through hole), and termination style (PC Pin). The primary difference is product status change from obsolete to active.

Q: What are the key differences between the C&K 1101M2S2V3RE2 and the Grayhill 48ASSP1S1V2QAT? A: The primary differences are: (1) mounting type—C&K uses through-hole while Grayhill uses panel mount; (2) current rating—C&K is rated 6A while Grayhill is rated 5A; (3) actuator length—C&K is 3.20mm while Grayhill is 5.08mm; (4) contact finish—C&K uses gold while Grayhill uses silver; (5) electrical life—C&K provides 40,000 cycles while Grayhill provides 30,000 cycles.

Q: Is the Grayhill 48ASSP1S1V2QAT suitable for applications requiring 6A current? A: The Grayhill part is rated for 5A maximum. Applications requiring sustained 6A operation should use the C&K 1101M2S2V3RE2. The Grayhill part may be acceptable for applications with peak currents near 6A if average operating current remains below 5A, subject to thermal analysis.

Q: Do all substitute parts meet the same environmental and compliance standards? A: All parts listed are RoHS3 compliant and REACH unaffected. All maintain MSL rating of 1 (unlimited moisture sensitivity level). Operating temperature ranges differ: the original and C&K substitute operate -30°C to 65°C, while the Grayhill substitute operates -30°C to 85°C.

Q: What is the impact of the different contact finishes (gold vs. silver)? A: Gold-plated contacts (C&K parts) provide superior corrosion resistance and lower contact resistance, particularly beneficial in low-signal applications. Silver-plated contacts (Grayhill part) offer good conductivity but may oxidize over time in certain environments. For general switching applications at 6A, both finishes are functionally adequate.

Q: Can the panel mount Grayhill switch be adapted for through-hole PCB mounting? A: Panel mount and through-hole configurations are mechanically distinct. Direct PCB mounting of a panel mount switch requires custom mechanical adaptation and is not recommended for production applications. Use the through-hole C&K 1101M2S2V3RE2 for standard PCB integration.
