MP240D3 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The MP240D3 is an active Sensata-Crydom solid state relay (SSR) featuring SPST-NO (1 Form A) switching configuration with AC zero-cross output capability. Designed for through-hole mounting in 4-SIP package format, this component operates with 3–32VDC input and handles 3A load current across 24–280V AC output range. The part maintains ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts may be required due to inventory constraints, application-specific voltage requirements, or packaging preferences while maintaining equivalent electrical and mechanical functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment across the following critical parameters:

• Circuit configuration (SPST-NO / 1 Form A)
• Output type (AC, Zero Cross)
• Load voltage range (24–280V minimum)
• Load current rating (3A or higher)
• Package format (4-SIP)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Compliance certifications (ROHS3, REACH Unaffected)

Input voltage range, load current capacity above minimum threshold, and packaging format (bulk vs. box) are secondary considerations that do not disqualify substitution when primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

GA8-6B02 qualifies as a direct substitute for MP240D3. Both parts are manufactured by Sensata-Crydom, share identical circuit configuration, output type, load voltage range, and package specifications. GA8-6B02 provides enhanced load current capacity (4.6A vs. 3A) and maintains equivalent input voltage coverage within the 3–28VDC range. Both parts carry ROHS3 compliance and unlimited MSL rating. Selection between these parts depends on inventory availability and packaging format preference (bulk vs. bulk).

ASR-SD240D3ZL functions as a similar substitute with equivalent electrical performance for the primary switching function. Manufactured by Altran Magnetics, LLC, this part maintains identical circuit configuration, output type, and load voltage specifications. Load current rating matches at 3A. The input voltage range (4–15VDC) is narrower than MP240D3 (3–32VDC), requiring verification that application input voltage falls within 4–15VDC bounds. MSL rating is not applicable for this part. All three parts maintain ROHS3 compliance and REACH unaffected status. Selection of ASR-SD240D3ZL requires confirmation that circuit input voltage does not fall below 4VDC or exceed 15VDC.

Frequently Asked Questions (FAQ)

Q: Can GA8-6B02 replace MP240D3 in any application? A: GA8-6B02 is a direct substitute when circuit input voltage remains within 3–28VDC. The higher load current rating (4.6A) provides additional margin. Verify that your application input voltage does not exceed 28VDC if currently using MP240D3 at the upper end of its 3–32VDC range.

Q: What is the primary limitation of ASR-SD240D3ZL as a substitute? A: ASR-SD240D3ZL has a restricted input voltage range of 4–15VDC compared to MP240D3's 3–32VDC range. This part is suitable only for applications where input voltage is confirmed to operate between 4VDC and 15VDC. Applications requiring input voltages below 4VDC or above 15VDC cannot use this substitute.

Q: Are all three parts pin-compatible? A: All three parts use 4-SIP package format with PC pin termination and through-hole mounting. Physical and electrical pin compatibility is maintained across MP240D3, GA8-6B02, and ASR-SD240D3ZL for direct PCB substitution.

Q: Do compliance certifications differ between these parts? A: All three parts maintain ROHS3 compliance and REACH unaffected status. ASR-SD240D3ZL does not carry an MSL rating, while MP240D3 and GA8-6B02 both specify MSL 1 (unlimited). For applications with moisture sensitivity concerns, MP240D3 or GA8-6B02 are preferred.

Q: Which substitute offers the best current capacity margin? A: GA8-6B02 provides the highest load current rating at 4.6A, compared to 3A for both MP240D3 and ASR-SD240D3ZL. For applications operating near the 3A limit, GA8-6B02 offers additional safety margin.
