RASM722 Equivalent & Substitute Parts

Part Overview

The RASM722 is a power barrel connector jack manufactured by Switchcraft Inc., designed for surface mount, right-angle applications. This connector features a 2.00mm ID (0.079") and 5.50mm OD (0.217") profile with solder termination. The part is currently in active production with 905 units available in new original stock.

Substitute parts are identified when they maintain functional compatibility within the allowed electrical and mechanical parameters for barrel connector applications, specifically matching the core mounting type, termination method, and contact configuration while accommodating standard tolerance variations in connector geometry.

Key Parameters

Substitute Part Grouping Explanation

The RASM722X qualifies as a direct substitute based on the following allowed parameter alignment:

Matching Parameters:

• Manufacturer: Switchcraft Inc. (same manufacturer)
• Category: Barrel Connectors
• Connector Type: Jack
• Gender: Male
• Number of Positions/Contacts: 2 Conductors, 3 Contacts
• Internal Switch(s): Single Switch, Normally Closed
• Mounting Type: Surface Mount, Right Angle
• Termination: Solder
• Shielding: Unshielded
• Current Rating: 5 A
• Contact Material - Plating: Tin
• Housing Material: Thermoplastic
• Contact Material: Copper Alloy
• Body Color: Black
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Tolerance Variation: The RASM722X accommodates a mating diameter of 2.10mm ID (0.083"), 5.50mm OD (0.217"), representing a standard tolerance variation from the RASM722 specification of 2.00mm ID (0.079"), 5.50mm OD (0.217"). This 0.10mm ID increase falls within acceptable mechanical tolerance ranges for barrel connector applications and does not affect electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RASM722 and RASM722X are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component applications. The RASM722X is designated as an active product with significantly higher inventory availability (10,546 units) compared to the RASM722 (905 units).

Selection between these parts should be based on application-specific mating connector specifications. The 0.10mm ID diameter difference between the two parts represents a standard tolerance variation within barrel connector design specifications. Both parts maintain identical electrical performance characteristics, including 5 A current rating, tin-plated copper alloy contacts, and single normally-closed switch configuration.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between RASM722 and RASM722X?

A: The primary difference is the mating diameter specification. The RASM722 features a 2.00mm ID (0.079") while the RASM722X features a 2.10mm ID (0.083"). Both maintain the same 5.50mm OD (0.217") specification. This represents a standard tolerance variation in barrel connector design.

Q: Are these parts electrically equivalent?

A: Yes. Both parts share identical electrical specifications including 5 A current rating, tin-plated copper alloy contacts, single normally-closed switch configuration, and unshielded design. Electrical performance is equivalent.

Q: Can RASM722X be used as a direct replacement for RASM722?

A: Compatibility depends on the mating connector specification in your application. If your mating connector is designed for 2.10mm ID barrels, RASM722X is the appropriate selection. If your application requires 2.00mm ID specifically, verify mating connector tolerance specifications before substitution.

Q: What is the packaging difference?

A: The RASM722 packaging specification is not provided. The RASM722X is supplied in bulk packaging.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both RASM722 and RASM722X are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component applications.

Q: Which part has better availability?

A: The RASM722X has significantly higher inventory availability with 10,546 units in stock compared to 905 units for the RASM722.
