Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101MPD9V3LE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole)
• Actuator type and length (Anti-Rotation, 6.86mm)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (100,000 Cycles)
• Base product number (7101MP)

The 7101MPD9V3RE meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement in applications currently using the obsolete 7101MPD9V3LE.

Parameter Comparison

Engineering Selection Recommendations

The 7101MPD9V3RE is the direct substitute for the obsolete 7101MPD9V3LE. Both parts share identical electrical and mechanical specifications, including current and voltage ratings, circuit configuration, and physical dimensions. The primary distinction is product status: the 7101MPD9V3RE is actively manufactured and supported, while the 7101MPD9V3LE is obsolete.

Both parts maintain equivalent compliance certifications. The 7101MPD9V3LE carries ROHS3 compliance, while the 7101MPD9V3RE carries RoHS compliance. Both are classified as REACH Unaffected or REACH Affected respectively, with identical moisture sensitivity levels and export classifications. For new designs and ongoing production, the 7101MPD9V3RE is the appropriate selection due to its active status and continued availability.

Frequently Asked Questions (FAQ)

Q: Can the 7101MPD9V3RE directly replace the 7101MPD9V3LE in existing applications?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including circuit configuration, current and voltage ratings, actuator dimensions, and termination style. Direct substitution is supported without circuit or layout modifications.

Q: What is the primary reason for substitution?

A: The 7101MPD9V3LE is classified as obsolete. The 7101MPD9V3RE is the active equivalent from the same manufacturer and series, ensuring continued supply chain access and manufacturer support.

Q: Are there any compliance differences between the two parts?

A: Both parts maintain equivalent compliance profiles. The 7101MPD9V3LE is ROHS3 compliant, while the 7101MPD9V3RE is RoHS compliant. Both carry EAR99 export classification and identical moisture sensitivity levels. Compliance differences do not affect functional substitution.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is based on equivalence across circuit configuration (SPDT), switch function (On-On), current rating (5A AC/DC), voltage ratings (120V AC, 28V DC), mounting type (Through Hole), actuator specifications (Anti-Rotation, 6.86mm), termination style (PC Pin), and operating temperature range (-30°C to 85°C).

Q: Are the through-hole mounting dimensions identical?

A: Yes. Both parts feature identical through-hole mounting specifications, including PC pin termination style and unthreaded bushing configuration, ensuring compatibility with existing PCB layouts.
