Key Parameters

Substitute Part Grouping Explanation

Substitution of the SC616JU is determined by strict equivalence across the following critical parameters: piezo technology classification, internally driven indicator circuitry, DC input type, 2.9kHz operating frequency, 68dB SPL @ 6V at 61cm measurement distance, panel mount configuration, screw terminal with 0.250" quick connect tab termination, 42.85mm diameter housing, and operating temperature range of -30°C to 65°C.

The SC616JU-1 qualifies as a direct substitute based on identical alignment across all specified mechanical and electrical parameters. Allowable variation exists only in current supply specification (2 ~ 12mA for SC616JU-1 versus fixed 12mA for SC616JU), which represents a compatible operating envelope rather than a functional deviation. Both parts maintain identical voltage range, frequency, sound pressure output, mounting configuration, and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The SC616JU-1 is the direct substitute for the obsolete SC616JU. Selection of SC616JU-1 is based on product status alignment: the main part is classified as obsolete, while SC616JU-1 maintains active status, ensuring continued availability and manufacturing support. Both parts are manufactured by the same supplier within the same SC series, maintaining design continuity.

Compliance considerations differ between the two parts. The SC616JU carries RoHS3 compliance status, while SC616JU-1 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must account for this distinction. Both parts maintain REACH Unaffected status, indicating no impact from REACH substance restrictions.

Current supply specification shows SC616JU-1 operates within a 2 ~ 12mA range, encompassing the fixed 12mA specification of SC616JU. This operational envelope ensures functional compatibility without modification to existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can SC616JU-1 be used as a direct replacement for SC616JU in existing designs?

A: Yes. SC616JU-1 maintains identical electrical and mechanical specifications across voltage range, frequency, sound pressure output, mounting configuration, and physical dimensions. The current supply range of 2 ~ 12mA for SC616JU-1 encompasses the 12mA specification of SC616JU, ensuring functional compatibility.

Q: What is the primary reason for substitution?

A: The SC616JU is classified as obsolete. SC616JU-1 is the active equivalent part from the same manufacturer and series, ensuring ongoing component availability.

Q: Are there compliance differences between SC616JU and SC616JU-1?

A: Yes. SC616JU is RoHS3 compliant, while SC616JU-1 is RoHS non-compliant. Applications requiring RoHS compliance must evaluate this distinction. Both parts maintain REACH Unaffected status.

Q: Do the parts have identical physical dimensions?

A: Yes. Both parts share identical panel mount configuration, 42.85mm diameter housing, 45.96mm maximum seated height, and 0.250" quick connect tab termination.

Q: Is circuit modification required when substituting SC616JU-1 for SC616JU?

A: No. Both parts operate at identical voltage range (6 ~ 16V), frequency (2.9kHz), and sound pressure output (68dB @ 6V, 61cm). The SC616JU-1 current range of 2 ~ 12mA is compatible with existing circuit designs.
