Sensata-Crydom 6402A AC Output Module - Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom 6402A is an AC output module designed for 5VDC input applications with 24–280VAC output capability at 3A current rating. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The module features hold-down screw mounting and operates with 1/2 cycle switching response times.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6402A is determined by the following critical parameters:

• Input voltage: 5VDC
• Output voltage range: 24–280VAC minimum
• Output current: 3A minimum
• Mechanical compatibility: Hold-down screw mounting
• Switching response: Cycle-based operation

Two substitute parts meet these criteria with varying degrees of parameter alignment:

OAC5A (Sensata-Crydom): Direct manufacturer alternative with identical input voltage, expanded output current (4.6A), matching output voltage range, and active product status.

OAC-5 (TE Connectivity Potter & Brumfield Relays): Cross-manufacturer alternative with identical input voltage and output current, but restricted output voltage range (12–120VAC versus 24–280VAC).

Parameter Comparison

Engineering Selection Recommendations

OAC5A Selection: This part is the primary substitute for the 6402A. Both components are manufactured by Sensata-Crydom, share identical input voltage specification, and maintain the full 24–280VAC output voltage range. The OAC5A provides increased output current capacity (4.6A versus 3A), offering design margin. Active product status ensures ongoing availability and supply chain continuity. ROHS3 compliance and REACH unaffected status align with modern regulatory requirements.

OAC-5 Selection: This part is a secondary substitute applicable only when output voltage requirements do not exceed 120VAC. The restricted output voltage range (12–120VAC) makes this part unsuitable for applications requiring the full 24–280VAC capability of the 6402A. REACH affected status may introduce regulatory considerations in certain markets. Selection of OAC-5 requires explicit verification that system output voltage demands fall within the 12–120VAC window.

Frequently Asked Questions (FAQ)

Q: Can OAC5A directly replace 6402A in all applications? A: OAC5A meets or exceeds all critical parameters of the 6402A: identical 5VDC input, full 24–280VAC output range, and 3A minimum current (OAC5A rated 4.6A). Mechanical compatibility via hold-down screw mounting is confirmed. Direct substitution is valid for applications matching the original 6402A specification.

Q: What is the key limitation of OAC-5 as a substitute? A: OAC-5 output voltage is limited to 12–120VAC, compared to the 6402A range of 24–280VAC. This part is suitable only for applications operating within the 12–120VAC window. Applications requiring higher output voltages (above 120VAC) cannot use OAC-5.

Q: How do switching times differ between the main part and substitutes? A: The 6402A specifies 1/2 cycle switching times. OAC5A and OAC-5 both specify 8.33ms switching times. These represent equivalent cycle-based operation at standard AC frequencies and are functionally compatible.

Q: Are there packaging differences between these parts? A: The 6402A packaging is not specified. OAC5A is supplied in bulk packaging, while OAC-5 is supplied in tray packaging. Packaging selection should align with procurement and assembly requirements.

Q: What compliance certifications should be considered? A: OAC5A holds ROHS3 compliance and REACH unaffected status. OAC-5 holds ROHS3 compliance but is REACH affected. For applications in REACH-regulated markets, OAC5A is the preferred choice.
