DMP6402A AC Output Module Equivalent & Substitute Parts

Part Overview

The DMP6402A is an AC output module manufactured by Sensata-Crydom, designed to switch AC loads up to 3A at voltages between 24 and 280VAC, with a 5VDC control input. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, redesign, and procurement planning. Substitute parts must maintain identical electrical performance characteristics while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DMP6402A is determined by strict equivalence across the following critical parameters:

• Input voltage: 5VDC (exact match required)
• Output voltage range: 24 ~ 280VAC (exact match required)
• Output current: 3A (exact match required)
• Component type: AC Output Module (functional category match required)

The two identified substitute parts, 70M-OAC5A and OACM-5, satisfy all four criteria. Both are active-status AC output modules with identical input/output voltage specifications and 3A current ratings. Differences in switching speed (1/2 cycle vs. 8.33ms), input current draw, packaging style, and compliance certifications do not affect functional substitutability for applications where the DMP6402A was originally specified.

Parameter Comparison

Engineering Selection Recommendations

Both 70M-OAC5A and OACM-5 are electrically equivalent to the DMP6402A and suitable for direct substitution based on core electrical parameters. Selection between the two alternatives should consider:

• Product Status: Both substitute parts are active-status components with confirmed current availability, eliminating obsolescence risk.
• Compliance Requirements: OACM-5 carries ROHS3 compliance certification, making it the preferred choice for applications subject to RoHS regulatory requirements. The 70M-OAC5A is RoHS non-compliant and should be selected only when RoHS compliance is not mandated.
• Inventory Availability: OACM-5 has 2,640 units in stock; 70M-OAC5A has 20,199 units in stock. Procurement timelines may favor the higher-inventory option.
• Packaging Format: 70M-OAC5A is supplied in bulk packaging; OACM-5 is supplied in tray packaging. Packaging selection depends on assembly process requirements and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can 70M-OAC5A and OACM-5 be used interchangeably with DMP6402A?

A: Yes. Both parts meet the electrical substitution criteria: 5VDC input, 24–280VAC output, and 3A output current. Physical form factor differences (SIP vs. Mini style) require PCB layout verification, but electrical performance is equivalent.

Q: What is the significance of the switching time difference (1/2 Cycle vs. 8.33ms)?

A: At 50Hz AC frequency, 1/2 cycle equals 10ms; at 60Hz, it equals 8.33ms. The substitute parts specify 8.33ms, which is faster than the DMP6402A at 50Hz operation but equivalent at 60Hz. Applications operating at 50Hz should confirm that faster switching does not introduce unintended transient effects.

Q: Does RoHS compliance matter for my application?

A: RoHS compliance is mandatory for products sold in the European Union and increasingly required by OEMs globally. If your application or supply chain requires RoHS certification, select OACM-5. If RoHS is not a requirement, either substitute is acceptable.

Q: Are there any input current differences I should account for?

A: The DMP6402A input current is not specified. The 70M-OAC5A draws 16 mA; OACM-5 draws 20 mA. Both values are typical for 5VDC control circuits and should not impact circuit design unless the control source has extremely limited current capacity.

Q: What packaging considerations apply to these substitutes?

A: DMP6402A uses SIP (Single In-line Package) style. Both substitutes use Mini style packages. Verify PCB footprint compatibility before committing to a substitution. Bulk packaging (70M-OAC5A) suits high-volume assembly; tray packaging (OACM-5) is standard for component handling and storage.
