PFE240D25 Equivalent & Substitute Parts

Part Overview

The PFE240D25 is a solid-state relay (SSR) manufactured by Sensata-Crydom in the PowerFin™ series. It functions as a SPST-NO (Single Pole Single Throw - Normally Open) relay with 25A load capacity and operates across 12V to 280V AC loads. The device features zero-cross switching for AC applications and is housed in a 4-SIP through-hole package with PC pin termination. This component is active in production and RoHS3 compliant. Equivalent and substitute parts are identified when they maintain identical or compatible electrical and mechanical specifications, ensuring functional interchangeability in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PFE240D25 are identified based on strict electrical and mechanical compatibility. The primary substitution criteria are:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Load Current: Must be rated for 25 A
• Load Voltage Range: Must support 12 V ~ 280 V AC operation
• Package / Case: Must be 4-SIP with PC pin termination
• Mounting Type: Must be Through Hole
• Output Switching: Must support AC operation

The identified substitutes are SSRF-240D25 and SSRF-240D25R, both manufactured by TE Connectivity Potter & Brumfield Relays. These parts meet all critical electrical parameters and physical form factors required for direct substitution in applications designed for the PFE240D25.

Parameter Comparison

Engineering Selection Recommendations

Both SSRF-240D25 and SSRF-240D25R are active production components with RoHS3 compliance and REACH unaffected status, matching the regulatory posture of the PFE240D25. All three parts share identical load current ratings, load voltage ranges, package configurations, and termination styles.

The primary distinction between substitutes lies in input voltage range and output switching characteristics. The PFE240D25 operates with 15 ~ 32 VDC input, while both TE Connectivity alternatives accept 3 ~ 15 VDC input. The SSRF-240D25 includes zero-cross switching for AC applications, whereas the SSRF-240D25R provides standard AC output without zero-cross specification.

Selection between substitutes depends on circuit input voltage requirements and whether zero-cross switching is functionally required in the application.

Frequently Asked Questions (FAQ)

Q: Can SSRF-240D25 directly replace PFE240D25 in existing designs?

A: SSRF-240D25 maintains identical load current (25A), load voltage range (12V-280V), circuit configuration (SPST-NO), package type (4-SIP), and termination style (PC Pin). However, the input voltage range differs: PFE240D25 requires 15-32VDC while SSRF-240D25 operates at 3-15VDC. Substitution is valid only if the circuit input voltage is compatible with the 3-15VDC specification.

Q: What is the difference between SSRF-240D25 and SSRF-240D25R?

A: Both parts share identical electrical ratings and physical form factors. The distinction is in output switching: SSRF-240D25 includes zero-cross switching for AC loads, while SSRF-240D25R provides standard AC output. Selection depends on whether zero-cross switching is required for the application.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts use 4-SIP through-hole packages with PC pin termination, enabling direct physical installation in PCB designs without modification.

Q: Do all substitutes meet the same compliance standards?

A: Yes. PFE240D25, SSRF-240D25, and SSRF-240D25R are all RoHS3 compliant, REACH unaffected, and rated MSL 1 (Unlimited). All three carry active product status.

Q: What is the critical parameter for determining substitutability?

A: Load current (25A), load voltage range (12V-280V), circuit configuration (SPST-NO), and package type (4-SIP) are the primary determinants. Input voltage range compatibility must be verified against circuit design specifications.
