Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SM05B-SRSS-TB is determined by strict alignment of the following critical parameters:

• Connector type: Header
• Contact type: Male pin
• Mating pitch: 0.039" (1.00mm)
• Number of positions: 5
• Number of rows: 1
• Mounting type: Surface mount, right angle
• Shrouding: Shrouded - 4 wall
• Termination: Solder
• Current rating: 1A
• Voltage rating: 50V
• Operating temperature range: -25°C ~ 85°C
• Material flammability rating: UL94 V-0
• RoHS compliance: ROHS3 Compliant

The CI1105M1HR0-NH manufactured by Cvilux USA meets all critical substitution parameters and is classified as an equivalent part for the SM05B-SRSS-TB.

Parameter Comparison

Engineering Selection Recommendations

Both the SM05B-SRSS-TB and CI1105M1HR0-NH are active production parts with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts should be based on:

• Packaging requirements: SM05B-SRSS-TB is supplied in Tape & Reel format; CI1105M1HR0-NH is supplied in Cut Tape format
• Fastening mechanism: SM05B-SRSS-TB uses push-pull fastening; CI1105M1HR0-NH uses detent lock fastening
• Inventory availability: CI1105M1HR0-NH has higher stock levels (15347 units versus 1410 units)
• Contact material specifications: SM05B-SRSS-TB uses copper alloy contacts; CI1105M1HR0-NH uses phosphor bronze contacts
• Insulation material: CI1105M1HR0-NH insulation is glass-filled and halogen-free

Both parts meet the electrical and thermal requirements for equivalent operation in board-to-cable/wire applications with 1A current capacity and 50V voltage rating across the -25°C to 85°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CI1105M1HR0-NH be used as a direct replacement for SM05B-SRSS-TB?

A: Yes. Both connectors share identical critical parameters: 5-position, 1.00mm pitch, surface mount right-angle headers with shrouded 4-wall design, solder termination, 1A current rating, 50V voltage rating, and -25°C to 85°C operating temperature range. Both are ROHS3 compliant with UL94 V-0 flammability rating.

Q: What are the differences between these two parts?

A: The primary differences are fastening type (push-pull versus detent lock), contact material (copper alloy versus phosphor bronze), insulation material composition (standard nylon versus glass-filled halogen-free nylon 6T), and packaging format (tape & reel versus cut tape).

Q: Does the fastening type difference affect compatibility?

A: Fastening type affects mating and unmating force characteristics but does not prevent electrical or mechanical compatibility. The choice between push-pull and detent lock depends on application requirements for connection security and ease of disconnection.

Q: Are there packaging considerations for these parts?

A: SM05B-SRSS-TB is supplied in Tape & Reel format suitable for automated assembly. CI1105M1HR0-NH is supplied in Cut Tape format. Packaging selection should align with manufacturing process requirements and volume needs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, UL94 V-0 rated, and have MSL 1 (Unlimited) moisture sensitivity level. Both operate across the same temperature range and voltage/current specifications.
