Substitute Part Grouping Explanation

The 38BC-0-H-3-S is qualified as a direct substitute for the 38BC-0-H-1-S based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

Electrical Compatibility:

• Identical circuit configuration (SPDT)
• Matching current rating (0.4VA AC/DC)
• Identical voltage ratings (20V AC and DC)
• Equivalent switch function (On-Momentary)

Mechanical Compatibility:

• Identical mounting type (Surface Mount, Right Angle)
• Matching termination style (Gull Wing)
• Same actuator type (Round, Plunger, Flush)
• Equivalent mechanical and electrical life ratings (80,000 cycles)

Environmental Compatibility:

• Identical operating temperature range (-30°C to 85°C)
• Matching sealing specification (Fully Sealed)
• Same moisture sensitivity level (MSL 1)

The primary distinction between these parts is the RoHS compliance status, with the substitute part offering ROHS3 compliance compared to the main part's non-compliant status.

Parameter Comparison

Engineering Selection Recommendations

Both the 38BC-0-H-1-S and 38BC-0-H-3-S are active production parts manufactured by Grayhill Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements:

For applications requiring RoHS3 compliance: The 38BC-0-H-3-S is the appropriate selection, as it meets ROHS3 compliance standards while maintaining all electrical and mechanical parameters of the primary part.

For applications without RoHS compliance requirements: Either part is functionally equivalent. The 38BC-0-H-1-S remains available with current inventory of 891 units.

Both parts maintain REACH Unaffected status and EAR99 export classification. The identical HTSUS code (8536.50.9031) confirms tariff classification equivalence. Inventory availability for the substitute part (1077 units) provides additional sourcing flexibility.

Frequently Asked Questions (FAQ)

Q: Can the 38BC-0-H-3-S be used as a direct replacement for the 38BC-0-H-1-S in existing designs?

A: Yes. The 38BC-0-H-3-S is electrically and mechanically identical to the 38BC-0-H-1-S. Both parts feature identical SPDT circuit configuration, 0.4VA current rating, 20V voltage rating, surface mount right-angle mounting, gull wing termination, and 80,000-cycle life ratings. No design modifications are required for substitution.

Q: What is the primary difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 38BC-0-H-3-S is ROHS3 compliant, while the 38BC-0-H-1-S is RoHS non-compliant. All other electrical, mechanical, and environmental specifications are identical.

Q: Are the actuator and sealing specifications identical between these parts?

A: Yes. Both parts feature round, plunger, flush actuators in white color with fully sealed enclosures. Operating temperature range (-30°C to 85°C), moisture sensitivity level (MSL 1), and mechanical/electrical life ratings (80,000 cycles) are identical.

Q: Do these parts have the same termination style and mounting configuration?

A: Yes. Both the 38BC-0-H-1-S and 38BC-0-H-3-S use gull wing termination and surface mount, right-angle mounting. They are mechanically interchangeable in PCB layouts designed for either part number.

Q: Which part should be selected for new designs?

A: For new designs, the 38BC-0-H-3-S is recommended due to its ROHS3 compliance status, which aligns with current regulatory requirements in most markets. Both parts are active production items with adequate inventory.

Q: Are there any differences in export classification or tariff codes?

A: No. Both parts share identical ECCN (EAR99) and HTSUS codes (8536.50.9031), confirming equivalence for export and tariff purposes.
